Fourier Analytic Approach to Quantum Estimation of Group Action [PDF]
Masahito HayashiThis article proposes a unified method to estimation of group action by using the inverse Fourier transform of the input state. The method can be applied to the non-commutative group as well as the commutative group. We show the square speed up phenomena of the estimation of the shift parameter in the energy constraint under the bosonic system.View original: http://arxiv.org/abs/1209.3463
